Gas-assisted injection molding can effectively produce parts free of sink marks in thick sections and free of warpage in long plates. This research investigated the basic filling phenomena in a gas-assisted injection molding process with flow visualization. A high-speed video camera was used to reco

A numerical algorithm is developed to simulate the injection-compression molding (ICM) process. A Hele-Shaw fluid-flow model combined with a modified control-volume/finite-element method is implemented to predict the melt-front advancement and the distributions of pressure, temperature, and flow vel
This paper is concerned with the practical application of closed-loop control on the gas pressure during the gas-assisted injection molding process. In principle, the gas-injection process can be treated as a valve-controlled tank charging. One of the critical factors for the successful application
